I have religious friends, but really, most of them are no problem. Most of the younger Christians/spiritual people I know don't really care if I'm a believer or not.
I sometimes wonder exactly what some of these younger Christians believe in. I have one friend who's, I think, 24. He always talks to me about his faith in Jesus, but at the same time lives with his girlfriend, usually gets drunk once or twice a week, does mild drugs (weed) and can't complete a sentence at times without one or two four-letter words
Family and older people are a different story completely when it comes to caring what I believe in. They're ready for a holy war, or better, god to rapture them up to heaven away from us heathens.
